MC14LC5480 - 5 V PCM Codec-Filter

Description

A PCM Codec

Filter is used for digitizing and reconstructing the human voice.

These devices are used primarily for the telephone network to facilitate voice switching and transmission.

Features

  • This allows input signals that are referenced to the V SS pin to be level shifted to the VAG pin with minimum noise. This pin may be connected to the VAG pin for an inverting amplifier configuration if the input signal is already referenced to the VAG pin. The common mode range of the TI+ and TI.
  • pins is from 1.2 V, to V DD minus 2 V. This is an FET gate input. Connecting the TI+ pin to V DD will place this am- plifier’s output (TG) into a high.
  • impedance state, thus allowing the.

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC14LC5480/D Advance Information 5 V PCM Codec-Filter The MC14LC5480 is a general purpose per channel PCM Codec–Filter with pin selectable Mu–Law or A–Law companding, and is offered in 20–pin DIP, SOG, and SSOP packages. This device performs the voice digitization and reconstruction as well as the band limiting and smoothing required for PCM systems. This device is designed to operate in both synchronous and asynchronous applications and contains an on–chip precision reference voltage. This device has an input operational amplifier whose output is the input to the encoder section.
